orchestrate direct transformation of 2-nitrobenzyl alcohols to quinolines under mild conditions with significant efficiency even when employed at a minimal catalyst loading of 0.1 mol %. Proportional experiments carried out with the corresponding mononuclear complex Ru3 by keeping the Ru content the same (0.2 mol % of Ru3) reveal superior activity by the bimetallic system Ru1 for the one-pot quinoline
双核 Ru(II) 配合物 [(p-伞花烃) 2 (RuCl) 2 L 1 ]2X (X = BF 4 (Ru1); X = PF 6 (Ru2)) 和单核 [(p-伞花烃)(RuCl)L 2 ]BF 4 (Ru3) (其中 L 1 = N,N'-(3,3',5,5'-四异丙基-[1,1'-联苯]-4,4'-二基)双(1-(吡啶) -2-基)甲亚胺);L 2 = N-(2,6-二异丙基-苯基)-1-(吡啶-2-基)-甲亚胺)已被合成并通过光谱和分析表征技术。双核 Ru1 和 Ru2 在温和条件下协调 2-硝基苯甲醇直接转化为喹啉,即使在 0.1 mol% 的最小催化剂负载量下使用,也具有显着的效率。通过保持 Ru 含量相同(Ru3 的 0.2 mol%),用相应的单核配合物 Ru3 进行比例实验,结果表明双金属体系 Ru1 对于一锅法喹啉合成具有优异的活性。生物活性类固醇的后期功能化和放大
